The Zetasizer
Nano ZS brings you the practicality of a maintenance-free system with the
versatility of multi-parameter measurements in a single compact unit.
Particle Size
Non-invasive back scatter (NIBS) technology takes particle sizing to new
levels of sensitivity in the 0.6nm to 6 micron range. The new Zetasizer
Nano ZS is the choice for the accurate, reliable and repeatable size analysis
of particles and molecules in solution.
Zeta potential
The new Zetasizer
Nano ZS offers the highest ever sensitivity, accuracy and resolution for
the measurement of zeta potential. This is achieved by a combination of laser
Doppler velocimetry and phase analysis light scattering (PALS) in Malvern's
patented M3-PALS technique. Even samples of very low mobility can be analyzed
and their mobility distributions calculated.
Chromatography
flow-mode
Connect the Zetasizer
Nano to your chromatography system for use as an absolute light scattering
detector. Just position after the last detector in your SEC/ GPC system. The
size and intensity are plotted in real time as the material is eluted from the
column. Averages, peak positions and molecular weights of each peak are calculated
automatically at the end of the measurement.
Molecular weight
Using static light scattering (SLS) and
the classical Debye plot, the molecular
weight of random coiled polymers up to
5 x 105 Da as well as globular polymers
and proteins up to 2 x 107 Da can be
determined without the necessity for
multi-angle measurements.
